FTL: Faster Than Light

You can do this quite easily with the Fire Bomb or the Fire Beam but you need to take care of not destroying the ship OR killing the crew before all squares are filled.

This is why I chose to try it against a Rockman ship, since they wont be able to die because of the fire. I had to kill their crew until one was left so they couldnt extinguish the fire fast enough.

Be careful of destroying their Oxygen system too quickly, if you destroy the o2 early in the attack, the fires may extinguish due to the lack of oxygen.

I had fun with this one 😃

To grab this achievement you have to unlock all 9 unlockable ships in the game, requirements vary but in general, if you complete the game with one type, you unlock another. The Crystal Cruiser is the hardest one to unlock, check the requirements below.

Just some clarifications I thought it would be useful to know before tackling this achievement since the description doesnt tell you about it.

Unlocking Clash of the Titans requires the enemy Rock ships to be completely destroyed, so killing all the enemy crew, accepting surrender or letting the enemy ship flee the battle does not count as destroyed ships.

The phrase "Rock ships" refers to the ship's class, not to its crew. This means pirate ships that are Rock-type will be included in the total if they are destroyed.

All 10 ships must be destroyed in a single playthrough.

Fastest way to do this one is with the Mantis Cruiser as they start with a teleporter.

Find an enemy ship, fight until its almost destroyed, teleport your guys in, blow it up.

I recorded this video as an example

You need the Stealth Ship unlocked and powerful weapons, that can deal at least 10 damage total to the hull (This type of enemy doesnt have shields)

Even in Sector 6 or 7, you might find these weak scout ships which can be easily destroyed within the 15 seconds the 3rd Cloaking upgrade gives you.

In my run, I had a small beam, a halberd and a burst 3.

(2+6+5 damage, I obliterated that ship)

Strangely enough, i did not unlock [Slice and Dice], Im pretty sure it was because the ship exploded before one of the lasers damaged the rooms as it should.

I could have unlocked them both if I didnt use the Burst weapon. So keep this in mind if you want to get both in one go.

To unlock the Stealth Ship, you need to have completed the Engi Ship Quest OR complete the game with the Rock Cruiser.

Remember to cloak!

Even in Sector 6 or 7, you might find these automated rebel scout ships, they have no shields and are prime for this achievement along with [Bird of Prey] if you are playing with the Stealth Cruiser, you can see that enemy ship in the video that is embedded in the Bird of Prey guide.

But the one in this guide's video does have shields, lucky for me, since Im almost at the endgame, I have powerful weapons by now to overcome their shields and use my laser beams effectively.

I have a Burst 3 weapon that can destroy shields no problem, my only concern is that the ship might explode before the laser beams would hit all rooms.

If the ship blows up before the beams hit all rooms, the achievement wont unlock.

Having one Halberd is strongly recommended as it spans three rooms.
The Mini Beam hits two, the stealth cruiser comes equipped with one.

I got lucky in this one and the enemy ship survived the beam attacks, giving me the achievement.
